An elevator is a permanent transportation device that serves a number of specific floors in a building and whose car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination Angle of less than 15° from the plumb line. There are also stepped, step plate mounted on the track continuous operation, commonly known as escalators or automatic walkways. Fixed lifting equipment for the specified floor. A vertical lift has a car that runs between at least two vertical or rigid rails with an inclination of less than 15°. The size and structure of the car make it easy for passengers to enter and exit or load and unload cargo. It is customary to use the elevator as a general term for vertical transportation in a building, regardless of its driving method. According to the speed, it can be divided into low-speed elevator (below 4 m/s), fast elevator 4 ~ 12 m/s) and high-speed elevator (more than 12 m/s). Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings. In 1852, the United States E.G. Otis developed a safety elevator with wire rope lifting.
